I'm not sure about whether you are physically able, but back in the past I walked home from work several times per week, i think it was over two miles, or 3. The long walk home was addictive because I had tapes of music I adore, to sing along to, and the walking released endorphins fairly soon into the walk. There were many days I danced across the bridge. It just had me feeling wonderful.
Anyway, I would get home still feeling great, and too early for the stores to open, so I spent less impulsively.
Whoever said you can't buy happiness is wrong. It can buy you days of amazing happiness, just using your entire body walking. Money can provide living in a good place, having good shoes, good medical care, healthy foods to eat, etc.
And for $5 or $10 you can buy a little kitten who ends up being your best friend and confidante for 20-something years. Money sure makes life easier.
